I need to test a software stability for one month under linux. Obviously, one month is too long . I am wondering, is there a tool that can accelerate this process, like if using this tool for 30 hours just like running this machine for one month (30 days)? Please be notice this tool should support linux. Thanks any reply in advance.

The way to do this kind of testing is to estimate the workload, and to increase it.
Eg, heat and cool the system in extreme conditions, perhaps use a wind tunnel, or a heat source, whatever is needed to simulate "one month" of use.
On a more serious note, what kind of load are you expecting? Eg, will you have a person sit and use the program each day, and therefore need to worry about changing dates while the application is still in use?
Or will you expect 50,000 customers over the span of one month?

I want to implement honey pot in our lab.
Actually it is a part of my work in our institution.
So I need some help and suggestion for the same.
"A server that is configured to detect an intruder by mirroring a real production system. It appears as an ordinary server doing work, but all the data and transactions are phony. Located either in or outside the firewall, the honeypot is used to learn about an intruder's techniques as well as determine vulnerabilities in the real system"
In practice, honeypots are computers which masquerade as unprotected. The honeypot records all actions and interactions with users. Since honeypots don't provide any legitimate services, all activity is unauthorized (and possibly malicious). Talabis presents honeypots as being analogous to the use of wet cement for detecting human intruders

This pdf white paper gives detail how it can be implemented..

I know that I need to know at least C and Assembly. In your own opinion what else does one need to know apart from knowing how to program in C and Assembly efficiently? Are there any books you can suggest to get me started? I also read that you need to know about the hardware architecture of the platform you are emulating. Would you also recommend the books listed here?
For experts only
You would have to know all the inner workings and hardware details of PSP, which are business secrets of Sony and therefore not published. The way most emulators are made is reverse engineering, a process in which the device itself is disassembled and its inner workings are studied. That includes analyzing the chips thoroughly, reading the contents of ROM chips and sometimes even deciphering encrypted data. Full analysis usually requires specialized equipment and years of engineering experience.

You are given 100 stations and distance between each adjacent stations. Now you have to select 10 stations(means 10 hops) among those 100 stations in such a way that maximum of distance between any 2 hops will be minimised. By default 1 and 100 stations are selected , so you need to choose only 8 more stations.
Since you haven't told us:
I'll assume time isn't an issue
I'll assume memory isn't an issue.
I'll assume the answer isn't programming language specific
I'll assume you are aiming to get from one station (1) to a destination station (100)
//Iterate through all possible paths to destination
//If you take more than 8 steps, stop and go back
//Note the total length of each path
//Select the shortest path
You're question is impossible difficult to answer, as such, my answer is rather impossible to understand. You will need to learn how to ask questions to get decent answers.
While you're at it, learn to accept answers
You are going to need to give us a question. It looks like you are being asked a question for an interview and then want us to give it to you to reiterate to an employer. It is pretty easy though, i have a similar program on my home pc implementing a few different path finding techniques.

Can anyone tell me links for reading about mainframe internals like what happens in mainframe intrenally when I login or create a dataset or submit a job. I googled but couldnt find
Thanks in advance
The Principles of Operation will give you as low-level a look at mainframe internals as you're likely to get.
You mention wanting to know what happens internally "when I login or create a dataset or submit a job." You might want to ask yourself, "login to what?" exactly. TSO? CICS? IMS?
For creating datasets you might start with DFSMS.
For submitting jobs you might want to start with JES2 or JES3, depending on which one you're using.
None of what you're asking is a small topic.
A mainframe is fundamentally just like any other computer - it is just a matter of scale that differentiates a mainframe from a desktop. Fundamentally, what happens when you log in to a Windows desktop is very similar to what happens when you log in to a mainframe. The details are very different but fundamentally you are doing the same thing.
The links cschneid provided in his answer will give you a lot of the finer detail, but conceptually, what goes on inside a mainframe is similar to what goes on in any computer these days.

I was just wanting to go ahead and make an OS. Because working on projects makes one's knowledge quite good enough. I know I will have to study OS inside-out before actually trying to implement one on my own. I also know I wouldn't be able to implement something right from square one. So I searched the internet for something to work upon. The most common option that I found was to work upon existing Linux distro and contribute to it.
But I found some more interesting options. Would like your suggestions on what to choose for and work upon.
LFS: http://www.linuxfromscratch.org/lfs/
PintOS: http://www.scs.stanford.edu/10wi-cs140/pintos/pintos_1.html#SEC1
Cosmos: http://www.gocosmos.org/index.en.aspx
I would get around 6 months time to work upon it. But before I start off with it, I want to do my research work properly and finalize what and how to work.
Drop in your suggestions on what should I use to work on. :)
